Abstract: Apparatus for the preparation of homogeneous mixtures from liquid components which may have different viscosities, which comprises a dynamic saturation/blending loop (14), having a small volume, in the feed line (12) feeding a bottle-filling machine, between a feeding pump (10) of the latter and the bottle-filling machine, in which loop the saturation/blending mixture, having a reduced volume, circulates continuously. The apparatus comprises a pump (20), said pump ensuring a minimum flow rate which is higher than the flow rate of the bottle-filling machine, and ensuring the circulation of the mixture in said dynamic loop (14), a storing loop (9), and a separator (27), which ensures the delivery of the homogeneous mixture toward the feed line (12) for feeding the bottle-filling machine.
